A die is tossed thrice. Find the probability of getting an odd number at least once.

Given: A die is tossed three times.

Then the sample space

Let probability of getting an odd number in first throw.

Let probability of getting an even number.

Now, probability of getting an even number in three times

So, the chances of obtaining an odd number at least once

– probability of getting an odd number in no throw

– probability of getting an even number in three times

Probability of getting an odd number at least once
